ATTINY44V-10MUR

Overview

The ATTINY44V-10MUR is an 8-bit AVR microcontroller featuring 4 KB of in-system programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates at a maximum clock frequency of 10 MHz with a supply voltage range of 1.8 V to 5.5 V. The device utilizes a 20-VFQFN package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrates advanced RISC architecture for efficient single-cycle instruction execution
• Provides non-volatile memory with high endurance for program and data storage
• Includes built-in analog-to-digital conversion and multiple timer/counters

Applications

• Battery-powered sensor nodes requiring low power consumption
• Industrial control systems operating within extended temperature ranges
• General-purpose embedded logic applications

Procurement Notes

Verify the specific suffix 'V' confirms the wide voltage operation range and 'UR' indicates the reel packaging format. Confirm the manufacturer status as Not Recommended for New Designs (NRND) to assess long-term availability risks before finalizing procurement plans.

Selection Notes

Select this component when a compact 20-pin form factor is required alongside moderate memory capacity. Ensure the design accommodates the 1.8 V minimum supply voltage if utilizing low-power battery sources. Verify that the 10 MHz speed meets the real-time processing requirements of the target application.

Part Context

This part belongs to the ATtiny44 family within the AVR microcontroller portfolio. It shares architectural similarities with the ATtiny24 and ATtiny84, differing primarily in memory sizes. The 'V' variant specifically denotes support for lower voltage operations compared to standard variants.

Replacement Considerations

Public confirmed substitute part numbers include ATtiny44PV-10MUR.
